STEPHEN A. WALTER, OF MOLINE, ILLINOIS, ASSIGNOR TO THE ACME MACHINE COMPANY, OF SAME PLACE.

DISH-CLEANER.

SPECIFICATION forming part of Letters Patent No. 511,920, dated January 2, 1894.

Application tiled February 6, 1893. Serial No 461,091. (No mocleLy To all whom t may concern.; vessel B is of somewhat smaller diameter than Be it known that I, STEPHEN A.

On the opposite side of the tank is setforth in mypatent hereinbefore mentioned. secured against movement a vertical rod D, The operation of myinvention is as follows: 95 shorter than the rod C. The tank is opened Into the tank A the requisite amount of water at its upper end and fromits bottom projects is placed and the vessel B having been lowan outlet of draw-off cock a2 by means of ered into the position shownin Fig. 2 and the which the tank may be emptied of dirty wabasket also lowered, a rotary motion is given 5o ter and cleansed when desired. The inner tothe basket by turning the crank Gr. The roo row in Fig. 3 causes arotary movement to be ,ing the same.

given the water which entering the bulge E dlverts the rotary course of the water and c auses the same to be directed-inwardly at right angles and through the open basket onto the dishes thereby cleaning them, which are subjected to a combined washing action due to the circular movement of the Water 1n the tank and the cross current due to the bulge. In my patent above mentioned I employ Wings to accomplish this result, but in some respects have found them objectionable. Occasionally the win gs will not fold open and will defeat the object for which they are used. In my present case Ifind that I obtain an increase of Water power and at the same time I secureapositiveaction- Theshipperisnowoperated to throw the pinion H into engagement with the crank handle, which latter being operated causes the pinion to raise the rack bar K and vessel B with the basket to the position shown in Fig. l the said devices being guided by the uprights C and D until the box b2 has passed off the end of the upright D. At this point in the operation the chain J becoming taut withdraws the latch J from its lug j and allows the vessel B to drop as shown in Fig. 2. The crank handle is now held while the shipper is operated to throw the ratchet face of the pinion into engagement with the ratchet teeth b3 of the casting and thereby hold the basket in its elevated position above the water in the tank whereby the dishes may be drained and subjected at all points to the atmosphere to assist in dry- If desired the cock of the spraying device may now be opened to allow a spray of hot water to be discharged upon the dishes. After having been thoroughly drained anddried the dish basket is swung outward as in my patent above mentioned as shown in Fig. 3, and from whence they may be removed.

Having thus described my invention, Iv

said bulge being curved at its outlet end, of

a vessel fitted to slide vertically in said tank and having an opening corresponding to said bulge, a dish basket, means for rotating said basket, and means for elevating the vessel and the basket substantially as herein described.

3. In a dish washing machine, the combif nation with the tank, a vessel adapted to slide vertically therein, a dish basket connected with saidI vessel, to move upwardly therewith and means for automatically releasing said vessel from said basket to allow the vessel to drop within said tank when the basket has reached a predetermined height, substantially as herein described.

4:. In a dish washing machine, the combination with a tank,'of a vessel within the tank,

a latch carried by the vessel a basket inclosedv within said vessel, a casting, mechanism supported thereby for elevating said basket and vessel, a lug carried by the casting with which the latch ,is engaged and a'chain secured to the catch and the tank to automatically disengage the latch from thelg when the vessel has reached a predetermined height, substantially as herein described.
